TensorFlow(GPU)libcudart.so.7.5错误 - 无法打开共享对象文件

Question

在Ubuntu 14.04上使用GPU安装TensorFlow.对于Ubuntu/UNIX环境来说相当新,所以很多东西我都没有.在搜索此问题时,我遇到了在安装了CUDA 7.5时无法导入CUDA 7.0的实例(因为TensorFlow不支持7.5).我安装了CUDA 7.0,但它似乎在寻找7.5 - 这是为什么？我在.bashrc文件中有以下几行:

export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/cuda-7.0/lib64"
export CUDA_HOME=/usr/local/cuda-7.0

但我仍然看到下面的问题......任何人都有任何建议吗？

您需要从SOURCE安装 TensorFlow来配置设置。通过 pip 或 easy_install 安装将不起作用。

使用 pip 将tensorflow从0.6.0升级到0.7.1后，我遇到了同样的问题。
